enter the vehicle in an emergency.
As a safety precaution, remove the key from 
the ignition or take the electronic key with you 
when leaving the vehicle, even for a short 
time.
Purchasing a second-hand vehicle

Be aware of the risk of theft of the vehicle if 
the key is present in one of the defined areas 
while the vehicle is unlocked. 
Accumulations (water, dust, grime, salt,  etc.) on the inner surface of the door 
handle may affect detection.
If cleaning the inner surface of the door 
handle using a cloth does not restore 
detection, contact a CITROËN dealer or a 
qualified workshop.
A sudden splash of water (stream of water, 
high pressure jet washer, etc.) may be 
identified by the system as the desire to open 
the vehicle.

Ease of use and comfort
3Front seats
Correct driving position
For safety reasons, adjustments must 
only be made when the vehicle is 
stationary.
Before taking to the road and to make the most 
of the ergonomic layout of the instruments and 
controls, carry out these adjustments in the 
following order:
–
 
head restraint height.
–
 
seat backrest angle.
–
 
seat cushion height.
–
 
longitudinal seat position.
–
 
steering wheel height and reach.
–
 
rear view mirror and door mirrors. 
 
Once these adjustments have been 
made, check that the instrument panel 
can be viewed correctly from your driving 
position.
Adjustments Forwards-backwards
 
 
► Raise the control bar and slide the seat 
forwards or backwards.
►
 
Release the bar to lock the seat in position on 
one of the notches.
Before moving the seat backwards, 
ensure that there is nothing that might 
prevent the full travel of the seat.
There is a risk of trapping or pinching 
passengers if present in the rear seats or 
jamming the seat if large objects are placed 
on the floor behind the seat.
Backrest angle 
 
► Turn the knob to adjust the backrest.
Height 
 
► Pull the control upwards to raise the seat or 
push it downwards to lower the seat, until the 
position required is obtained.

Ease of use and comfort
Steering wheel 
adjustment
 
 
► When stationary, lower the control A to 
release the steering wheel.
►  Adjust the steering wheel height and reach to 
suit your driving position.
►  Raise the control  A to lock the steering 
wheel.
As a safety precaution, these operations  should only be carried out while the 
vehicle is stationary.
► Turn the knob manually to obtain the desired 
level of lumbar support.
Head restraint height 
adjustment
 
 
► To raise it, pull it upwards as far as possible 
(notch).
►
 
T
 o remove it, press the lug A and pull it 
upwards.
►
 
T
 o put it back in place, engage the head 
restraint rods in the openings keeping them in 
line with the seat backrest.
►
 
T
 o lower it, press the lug A and push down on 
the head restraint at the same time.
The head restraint has a frame with  notches which prevents it from lowering; 
this is a safety device in case of impact.
The adjustment is correct when the upper 
edge of the head restraint is level with the 
top of the head.
Never drive with the head restraints removed; 
they must be fitted and correctly adjusted.
Heated seats  
 
 
► With the engine running, use the adjustment 
knob to switch on and select the level of heating 
required:
0
 
: Off.
1
 
: Low.
2
 
: Medium.
3
 
: High.
The front seats can be heated individually.
Before leaving the vehicle, ensure that 
the adjustment knob of the passenger 
seat is at position
  0, so that the heating does 
not unnecessarily operate if no passenger is 
present during the next journey.
Do not use the function when the seat 
is not occupied.
Reduce the heating intensity as soon as 
possible.
When the seat and passenger compartment 
have reached a satisfactory temperature, 
switch the function off; reducing electricity 
consumption in turn decreases fuel 
consumption.
Prolonged use of the heated seats is not 
recommended for those with sensitive 
skin.
There is a risk of burns for people whose 
perception of heat is impaired (illness, taking 
medication, etc.).
To keep the heated pad intact and to prevent 
a short circuit:
–
 
do not place sharp or heavy objects on the 
seat,
–
 
do not kneel or stand on the seat,
–
 
do not spill liquids onto the seat,
–
 
never use the heating function if the seat 
is wet.
